A couple weeks ago, I attempted to open the thru hull valve for the galley sink/ice box drain. The valve was frozen (fortunately closed). There was nothing that I could do to open the valve - - including using my “persuader” from the tool box. All that did was rotate the handle – not the valve’s ball. So, the valve needed to be replaced. The same day, the Flipper pump for the galley gave up the ghost too. The pump would not hold a prime, wobbled like crazy and once a prime got going the faucet pipe popped out of the top of the pump…… Can you spell fountain??? So, the Flipper needed to be replaced also.
I shopped around and found that Catalina Direct had the best prices. So, ordered both. The valve and Flipper came UPS on Tuesday this week. And I headed out to the marina on Thursday morning. These are two fairly straight forward jobs, wouldn't you say. I say BOAT - - and that means no repair/replacement goes straight forward and easy.
With Snickerdoodle in the water, my brother Bob helped with the thru hull valve. Replacing the valve while the boat was in the water went fine after I got the drain hoses disconnected from the "T" on top of the valve. That took a lot of effort. The hoses were on quite tight. The trick to replacing the valve is to stop the in-flow of water with a paper towel plug that is pushed into the thru hull fitting. Nearly all of the fountain is reduced to a small trickle. So, replacing the valve goes easily after that. Once the valve was secure, simply open the valve and push the paper towel out the bottom of the boat with a small dowel. Bob and I went to lunch after that job to let the repair "settle in" and make sure that nothing was leaking.
After lunch I went back to Snickerdoodle to replace the Flipper pump. Unfortunately, when the pump was originally installed at the factory, someone either got the fastening nut cross threaded or used glue to fix it in place. There was no way that I could get the nut off - - even with a set of BIG channel lock pliers. So, I gave up Thursday afternoon and drove back to Spokane. On the way to town, I had sort of an epiphany - - - I could buy one of those hacksaw handles and cut the pump off just above the drain board. And that's what I did Friday morning. Replacing the Flipper was now easily accomplished. The thru hull valve works just right - and without leaks... The new Flipper pumps perfectly and right into the sink.
I was smart too in that I took the galley drawers and frames off so that I had much bigger openings to work in. BOY!!! I'm sure glad I thought of that. So, the boat is all set for our cruise around the lake next week

No boat project is as small as it appears it will be! I replaced my transom-mounted depth transducer and ran the cable into the boat... But where is the connector from the cable that goes down from the display? It looks like they built the boat around it.
